Thanks, I have never trusted truck stop DEF so its good to hear others feel the same way.
Thanks for the info, the percentage at 17000 helps out. I wonder how they get a %.
I'm Tom and I have a 2022 Ram 1500 EcoDiesel. I am thinking I need to check on maintenance of my DEF system. This is my first diesel and I have done all the mainenance so far. What do I need to check to keep my truck in top operating condition?
